From Literary Hub:
1) Write. There is no substitute. Write what you most passionately want to write, not blogs, posts, tweets or all the disposable bubblewrap in which modern life is cushioned. But start small: write a good sentence, then a good paragraph, and don’t be dreaming about writing the great American novel or what you’ll wear at the awards ceremony because that’s not what writing’s about or how you get there from here. The road is made entirely out of words. Write a lot. Maybe at the outset you’ll be like a toddler—the terrible twos are partly about being frustrated because you’re smarter than your motor skills or your mouth, you want to color the picture, ask for the toy, and you’re bumbling, incoherent and no one gets it, but it’s not only time that gets the kid onward to more sophistication and skill, it’s effort and practice. Write bad stuff because the road to good writing is made out of words and not all of them are well-arranged words.

5) Find a vocation. Talent is overrated, and it is usually conflated with nice style. Passion, vocation, vision, and dedication are rarer, and they will get you through the rough spots in your style when your style won’t give you a reason to get up in the morning and stare at the manuscript for the hundredth day in a row or even give you a compelling subject to write about. If you’re not passionate about writing and about the world and the things in it you’re writing about, then why are you writing? It starts with passion even before it starts with words. You want to read people who are wise, deep, wild, kind, committed, insightful, attentive; you want to be those people. I am all for style, but only in service of vision.
6) Time. It takes time. This means that you need to find that time. Don’t be too social. Live below your means and keep the means modest (people with trust funds and other cushions: I’m not talking to you, though money makes many, many things easy, and often, vocation and passion harder). You probably have to do something else for a living at the outset or all along, but don’t develop expensive habits or consuming hobbies. I knew a waitress once who thought fate was keeping her from her painting but taste was: if she’d given up always being the person who turned going out for a burrito into ordering the expensive wine at the bistro she would’ve had one more free day a week for art.
